How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
Why cant you use the voltage across the inductor and the voltage across the lamp to find the supply voltage in a fluorescent fitting?
Because the two voltages are out of phase, that means that individually they peak at different times in the AC cycle, so in general if they are measured separately their sum will exceed the supply voltage, possibly by up to 41%.
What formula to find the emf and internal resistance for cell when given the current and the voltage?
I don't think you can do that, with the information provided.
When there are 10 mA of current through a 1.0k ohm resistor the voltage across the resistor is?
To find the voltage across a resistor, you can use Ohm's Law, which states that ( V = I \times R ). Here, ( I = 10 , \text{mA} = 0.010 , \text{A} ) and ( R = 1.0 , \text{k}\Omega = 1000 , \Omega ). Thus, the voltage is ( V = 0.010 , \text{A} \times 1000 , \Omega = 10 , \text{V} ). Therefore, the voltage across the resistor is 10 volts.
What should be the secondary voltage of a transformer needed in a rectifier circuit if the required DC voltage is 6 volts using a?
A little more than 6 volts RMS, or 17 volts peak to peak (can get -6 and +6 voltage this way using a full wave rectifier). The voltage will depend strongly on your design - are you using circuitry that clamps the output voltage to a specific value (you should!). If you are doing this, I would find the cheapest transformer that meets the current capacity you need that has an output near the 6 volts you want.
How do you find the string efficiency?
string efficiency= voltage across the string ---------------------------------------- (N*voltage across the most stressed unit) N is the number of units in the string

string efficiency= voltage across the string ---------------------------------------- (N*voltage across the most stressed unit) N is the number of units in the string
Find the output voltage of an amp whose input voltage is 0.05 volt and db gain is 35 db?
db gain is defined as power gain, not voltage gain. Please restate you question in terms of power, or provide details of input and output impedance.
How do you find the capacity of the fuel tank using voltage output. Actually I have a device where in i get the output of the fuel value inside the tank in the form of voltage. Please help?
Tell me what car the fuel tank is located in and I will tell you the fuel capacity.
How do you find resistors in parallel?

Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
Is it possible to find out how much voltage is stored in a solar cell?
Solar cells produce electricity rather than store voltage. The voltage produced by a solar cell depends on factors like sunlight intensity and cell characteristics. You can measure the voltage generated by a solar cell using a multimeter or similar device.
Is there a way to lower down the voltage output of a battery charger?
A: Simply by adding a series resistor from the battery charger. WHAT VALUE? find the current required and use it to IR drop the voltage

How do you find output wattage?
P(watts) = I (current) times E (voltage) hence it is known as the pie formula P=IE
Does a rectifier convert an AC voltage into a DC voltage?
Yes, a rectifier can be used to convert AC into DC.Using a single rectifier, half of a sine wave voltage can be clipped off, which leaves the other half. The voltage not steady as only half of the sine wave appears at the output during one cycle. This is half-wave rectification. A more complicated rectifier arrangement can force both halves of the AC input to be delivered in the output. One half of the sine wave will be "flipped over" so the output voltage does not change polarity.In neither case will the output voltage be "steady" and further "smoothing" circuitry will be required to make the DC output. This is the function of filtering, and many DC supplies will incorporate this feature. Lastly, we also find that DC supplies often incorporate some kind of regulation, which makes the output voltages resistant to changes when the input voltage changes and/or the load on the supply changes.
What is fill factor of photovoltaic cells?
The fill factor of a photovoltaic cell is a measure of its efficiency in converting sunlight into electricity. It is the ratio of the maximum power output of the cell to the product of its open-circuit voltage and short-circuit current. A higher fill factor indicates a more efficient solar cell.
